You can use the command-line interface
(CLI) to shut down a system.
Procedure
To power off your

- Determine which hosts have access to
volumes on this system by running the lshostvdiskmap command.
- Stop input/output (I/O) to the system from each host that is listed in step 1.
Note: Failure to stop host I/O can result in failed I/O operations being reported to your host
operating systems.

stopsystem
- Wait for the power light-emitting diodes (LEDs) on all node canisters in all control enclosures
to flash at 1 Hz, indicating that the shutdown operation has completed.
